Re: Casting the Result of splitter() into a string array

2012-06-17 Thread Trass3r

If you want to convert a range to an array, use std.array.array

This is a constant source of confusion and it also is a crappy design to  
use a function in a totally different module for this purpose imho.
Can't these Result types get an eval() method and/or be made implicitly  
convertible to an array where appropriate?

The C++ matrix library Eigen uses this approach and it works out  
a*b returns an object representing this expression. If I do want to use  
this I write 'auto c=a*b;'.
If I want the result I can explicitly use its eval() method (which is  
especially useful inside a bigger expression) or something like 'Matrix  
c=a*b;' which also evaluates the expression.

You could also show something that checks for an interface at  
compile-time, like

template isInputRange(R)
enum bool isInputRange = is(typeof(
R r;  // can define a range object
if (r.empty) {}   // can test for empty
r.popFront(); // can invoke popFront()
auto h = r.front; // can get the front of the range

CTFE is another strong feature.
You could for example show some code that generates Token handling code  
(an enum for the tokens, associative arrays for token 2 string and the  
other way around, etc.) to be used by a lexer without the necessity for a  
DSL like in Clang or a separate tool like dmd.

Re: contrary of std.utf.toUTFz!(const(wchar)*)

I feel a little stupid, but how to convert  a wchar* zero terminated  
string into a wstring (DMD 2.055)?

wstring w = cstr[0 .. strlenw(cstr)];

Just wanted to point out how it's implemented with language tools.

Cannot be compiled. Why?


Just use void* for opaque pointers in D.

Re: I can't build dsfml2 or derelict.sfml whit dsss

2011-09-22 Thread Trass3r

DSFML2's dsss file is just a remnant from the old DSFML.
Also I don't really update DSFML2 anymore. A SWIG wrapper would be a  
better idea but it's hard to make it use our custom system module instead  
of wrapping the original one.

In general using dsss isn't advisable, since rebuild is horribly outdated.

Re: toUTFz and WinAPI GetTextExtentPoint32W

2011-09-20 Thread Trass3r

bool test(HDC dc, string str, int len, SIZE* s)
wchar[] wstr = toUTFz!(wchar*)str;
GetTextExtentPoint32W(dc wstr.ptr, wstr.length, s);

toUTFz returns a wchar*, not a wchar[].

Re: toUTFz and WinAPI GetTextExtentPoint32W

2011-09-20 Thread Trass3r
Are you sure that the call requires the string to be null terminated? I  
do not know that winapi function, but this might work:

bool test(HDC dc, string str, SIZE* s)
auto wstr = to!(wchar[])str;
GetTextExtentPoint32W(dc, wstr.ptr, wstr.length, s);

It doesn't need to be null-terminated for that function.
Shouldn't you use to!wstring though?!

Just came across some old D code that does this:


Hundreds of OpenGL decls

in dmd 2.055, the extern(C) is not being applied to the OpenGL decls.
should it?

Walter once said it was deliberate.
That extern(C) is only valid inside the version block.
But I also think it should be the other way around.

Re: D, DLLs, UnrealScript and UDK (Sort of a complex question)

2011-09-19 Thread Trass3r

So, my question is THIS:

Can I write a windows DLL file in D that would have functions that can  
be accessible from a compiled C++ program?  (Actually, in this case, it's

UnrealScript that is compiled into a C++ exe.)

It's perfectly possible to create DLLs with D, also see

I already successfully used a D dll with C interface to create Matlab  
plugins as well as a D dll exposing a COM interface to hook DirectDraw.

Change it to the following, and you're golden.

That only fixes this particular issue.

Re: port c macro to D

When porting c-code to D, I come consitently to the problem,
how to convert such a c-macro:

#define V(a,b,c) glVertex3d( a size, b size, c size );
#define N(a,b,c) glNormal3d( a, b, c );
N( 1.0, 0.0, 0.0); V(+,-,+); V(+,-,-); V(+,+,-); V(+,+,+);

Ok, I could just write it out, but that's not the case.
Sometimes I just want to keep it small and clear as in this example.
I've started with some static functions and use it in mixins:

static string V(string a, string b, string c) {
return glVertex3d(~a~ size, ~b~ size, ~c~ size);
static string N(string a, string b, string c) {
return glNormal3d(~a~,~b~,~c~);;

If you are willing to write V(+1,-1,+1) instead you can just turn them  
into functions.

Also by static function you probably mean private in D.

No, I meant for mixin I nead static functions, but I just realized,
it also works without the static keyword.

I think static has no meaning in global scope, only in function scope  
where it tells the compiler you don't want a closure.
